Complex Position Size

For complex, multi-leg options positions comprising two or more legs, TWS might not track all changes to this position, e.g. a vertical spread where the short leg is assigned and the user re-writes the same leg the next day, or if the user creates a the position over multiple trades, or if the order is not filled as a native combination at the exchange.

If you received a message because you are submitting an order to close a position, roll a position, or modify a position using the “% Change” feature, it means that the maximum quantity of option positions in your account that are available to close for this order is different from that of the original position tracked by TWS.
Before submitting, you should review the order and confirm that the order quantity we have calculated is the correct quantity that you want to trade.

Dans quels cas envisager d'exercer une option d'achat avant expiration ?

INTRODUCTION

Exercer une option d'achat avant expiration ne présente, en règle générale, pas d'intérêt d'un point de vue financier. En effet :

  • cela conduit à une confiscation de la valeur temps de l'option pour la période restante ;
  • requiert une mobilisation plus importante de capital pour le paiement ou le financement de la livraison de l'action ; et
  • peut exposer le détenteur de l'option à un risque accru de perte sur l'action comparé à la prime de l'option.

Toutefois, pour les détenteurs de compte ayant la capacité de faire face à une exigence de capital ou d'emprunt plus importante ou à un risque accru de baisse du marché, il peut être intéressant de demander l'exercice anticipé d'une option d'achat américaine afin de bénéficier d'une distribution de dividende imminente.

RAPPEL

Le détenteur d'une option d'achat ne reçoit pas de dividende sur l'action sous-jacente car ce dividende revient au détenteur de l'action au moment de la date d'enregistrement (record Date). À la date  ex-dividende, le cours de l'action diminue normalement d'un montant égal à celui du dividende. Bien que la théorie sur le prix des options suggère que le prix d'un call reflétera la valeur réduite des dividendes qui doivent être payés durant la période, ce prix peut également baisser à la date ex-dividende.  Les conditions rendant ce scénario plausible et un exercice anticipé favorable sont les suivantes :

1. L'option est "deep-in-the-money" et a un Delta de 100 ;

2. L'option n'a pas ou peu de valeur temps ;

3. Le dividende est relativement élevé et la date ex-dividende précède la date d'expiration de l'option.

EXEMPLES

Pour illustrer l'impact de ces conditions sur une décision d'exercice anticipé, prenons l'exemple d'un compte avec une position longue en numéraire de 9,000 USD et une position longue d'options d'achat de l'action hypothétique  “ABC”  dont le prix d'exercice est 90.00 USD, avec une expiration dans 10 jours. Le dividende d'ABC, qui s'échange actuellement à 100.00 USD, est de 2.00 USD par action, avec une date ex-dividende le lendemain. Nous supposerons également que le prix de l'option et le cours de l'action se comportent de manière similaire et baissent du montant du dividende à la date ex-dividende.

Nous observerons les effets de la décision d'exercice visant à maintenir une position Delta de 100 actions et à maximiser la position. Deux prix d'options seront retenus, dans le premier cas, l'option est vendue à parité, dans le second, au dessus de la parité.

SCÉNARIO 1: Prix d'option à parité - 10.00 USD

Dans le cas d'une option s'échangeant à parité, l'exercice anticipé servira à maintenir la position Delta et à éviter une perte de valeur sur une action longue lorsque l'action trade ex-dividende pour préserver la valeur. Dans ce cas, les liquidités sont entièrement dédiées à l'achat de l'action au prix d'exercice, la prime de l'option est confisquée et l'action (nette de dividende) et le dividende à recevoir sont crédités sur le compte. Si vous souhaitez arriver au même résultat en vendant l'option avant la date ex-dividende et en achetant l'action, n'oubliez pas d'inclure les commissions/spreads dans vos calculs :

SCÉNARIO 1
Éléments du compte Solde de départ Exercice anticipé Aucune action Vente option & achat action

Total 10,000$ 10,000$ 9,800$ 10,000$ moins commissions/spread

 

 

SCÉNARIO 2: Prix d'option au-dessus de la parité - 11.00 USD

Dans le cas d'une option s'échangeant au dessus de la parité, un exercice anticipé afin de percevoir le dividende peut être avantageux. Dans un tel cas de figure, un exercice anticipé engendrerait une perte de 100 USD en valeur temps sur l'option, tandis qu'une vente de l'option et un achat de l'action, peut être, après commissions, moins avantageux que de ne rien faire.  Dans ce cas, la meilleure solution est de ne rien faire.

REMARQUE : Les titulaires de compte détenant une position longue d'options d'achat dans le cadre d'un spread doivent se montrer particulièrement vigilants quant au risque lié au non-exercice de la jambe longue compte tenu de la probabilité d'un exercice de la jambe short. Veuillez noter que l'assignation d'une option d'achat short entraîne une position short d'actions et les détenteurs de positions short d'actions à la date d'enregistrement du dividende ont l'obligation de payer un dividende au prêteur des actions. Par ailleurs, le cycle de traitement de la chambre de compensation ne permet pas la soumission de notifications d'exercice en réponse à une assignation.

Prenons l'exemple d'un spread créditeur d'options d'achat (bear) sur le SPDR S&P 500 ETF Trust (SPY) comprenant 100 contrats short avec un prix d'exercice de 146 USD à mars 2013, et 100 contrats long au prix d'exercice de 147 USD à mars 2013. Le 14 mars 2013, SPY Trust annonce une distribution de dividende de 0.69372 USD par action, payable le 30 avril 2013 aux actionnaires à une date d'enregistrement au 19 mars 2013. Compte tenu des 3 jours ouvrables de règlement pour les actions U.S., il aurait fallu acheter l'action ou exercer l'option d'achat au 14 mars 2013 au plus tard, afin de recevoir un dividende, étant donné que l'action commençait à trader ex-dividende le lendemain.

Le 14 mars 2013, alors qu'il restait un jour de trading avant expiration, les deux options s'échangeaient à parité, ce qui implique un risque maximum de 100 USD par contrat, soit 10,000 USD sur la position de 100 contrats. Cependant, ne pas exercer le contrat long afin de percevoir un dividende et de se protéger contre l'assignation vraisemblable des contrats short par d'autres intervenants en quête d'un dividende, a engendré un risque supplémentaire de 67.372 USD par contrat, soit 6,737.20 USD sur la position restante lorsque toutes les positions d'achat seront assignées. Comme indiqué dans le tableau ci-dessous, si la jambe de l'option short n'avait pas été assignée, le risque maximum au prix de règlement final au 15 mars 2013, serait resté à 100 USD par contrat.

Date Clôture SPY Option d'achat 146$ mars 2013 Option d'achat 147$ mars 2013
14 mars 2013 156.73$ 10.73$ 9.83$
15 mars 2013 155.83$   9.73$ 8.83$

Veuillez noter que si votre compte est soumis à une retenue fiscale dans le cadre de la règle du trésor américain 871(m), il peut être avantageux pour vous de fermer une position d'options longue avant la date ex-dividende et de la rouvrir après.

Annonce de résultats

Aux États-Unis, les sociétés cotées en bourse ont généralement l'obligation de publier leurs résultats tous les trimestres. Ces résultats contiennent de nombreuses informations telles que des statistiques, leur chiffre d'affaires, des données sur leurs marges et bien souvent, des projections concernant la rentabilité future de l'entreprise. Ces données peuvent avoir un impact significatif sur le prix des actions de ces entreprises. En ce qui concerne le trading d'options, tout ce qui est susceptible d'entraîner la volatilité d'une action affecte le prix des options. Les publications de résultats ne font pas exception à la règle.

Les traders d'options tentent souvent d'anticiper les réactions du marché aux annonces de résultats. Ils savent que la volatilité, facteur déterminant du prix des options, va régulièrement augmenter et que la polarisation (la différence de volatilité entre les options dans la monnaie et hors de la monnaie) va régulièrement s'accentuer à l'approche de la date d'annonce des résultats. Le degré d'ajustement de ces facteurs est souvent lié aux performances historiques. Les actions qui, dans le passé, ont enregistré des mouvements importants après l'annonce de résultats, ont souvent des prix d'options plus élevés.

Les risques liés à l'annonce de résultats sont idiosyncratiques, c'est-à-dire qu'ils sont généralement liés à l'action en elle-même et il n'est pas facile de s'en protéger par le biais d'un index ou d'une entreprise similaire. Des actions généralement fortement corrélées peuvent réagir différemment, ce qui aboutit à des prix d'actions divergents ou des indices présentant des mouvements moins importants. Pour cette raison, il n'existe pas de stratégie unique qui puisse s'appliquer au trading d'options dans ces circonstances. Les traders doivent avoir des attentes claires vis-à-vis des mouvements potentiels d'une action avant de décider quelle combinaison d'options est la plus à même de générer des gains si le trader a vu juste.

Si le marché semble trop positif vis-à-vis des perspectives de résultats d'une entreprise, il est relativement simple (bien que souvent coûteux) d'acheter un straddle ou un put hors de la monnaie et d'espérer qu'un mouvement important se produira. Tirer profit des perspectives inverses, lorsque les volatilités au mois le plus proche semblent trop importantes, peut également se révéler avantageux mais être en position courte sur une option est également susceptible d'engendrer des pertes importantes en cas de fort mouvement à la hausse de l'action. Les traders peuvent tirer profit d'une forte volatilité au mois le plus proche en achetant un calendar spread - ils  vendent un put avec échéance au mois le plus proche et achètent le même prix d'exercice le mois d'après. Le potentiel de profit maximum est atteint si l'action s'échange au prix d'exercice, tandis que l'option à échéance au mois le plus proche décline bien plus rapidement que l'option à long terme, plus chère. Les pertes sont limitées au prix de trading initial.

Parfois une polarisation extrême traduit des craintes excessives lorsque les options put hors de la monnaie affichent des volatilités de plus en plus élevées et supérieures aux options dans la monnaie. Les traders utilisant des spreads verticaux peuvent tirer profit de ce phénomène. Les traders baissiers peuvent acheter un put dans la monnaie et vendre un put hors de la monnaie. Cela permet à l'acheteur de payer une partie des coûts d'une option plus chère, bien que cela plafonne les profits générés par la transaction si l'action baisse en dessous du prix d'exercice le plus bas. D'un autre côté, ceux qui estiment que le marché est excessivement baissier peuvent vendre un put hors de la monnaie tout en achetant un put au prix d'exercice encore plus bas. Bien que le trader achète l'option présentant la plus forte volatilité, cela lui permet de gagner de l'argent tant que l'action reste au-dessus du prix d'exercice le plus haut, tout en limitant ses pertes à la différence entre les deux prix d'exercice.

Earnings

Publicly traded companies in North America generally are required to release earnings on a quarterly basis. These announcements, which contain a host of relevant statistics, including revenue and margin data, and often projections about the company's future profitability, have the potential to cause a significant move in the market price of the company's shares. From an options trading viewpoint, anything with the potential to cause volatility in a stock affects the pricing of its options. Earnings releases are no exceptions.

Options traders often try to anticipate the market's reaction to earnings news. They know implied volatilities, the key to options prices, will steadily rise while skew - the difference in implied volatility between at-money and out-of-the-money options - will steadily steepen as the earnings date approaches. The degree by which those adjustments occur is often based on history. Stocks that have historically made significant post-earnings moves often have more expensive options.

Earnings risk is idiosyncratic, meaning that it is usually stock specific and not easily hedged against an index or a similar company. Stocks that are normally quite well correlated may react quite differently, leading to share prices that diverge or indices with dampened moves. For those reasons, there is no single strategy that works for trading options in these situations. Traders must have very clear expectations for a stock's potential move, and then decide which combination of options will likely lead to the most profitable results if the trader is correct.

If the market seems too sanguine about a company's earnings prospects, it is fairly simple (though often costly) to buy a straddle or an out-of the-money put and hope for a big move. Taking advantage of the opposite prospect, when front month implied volatilities seem too high, can also be profitable but it can also cause serious losses to be short naked options in the face of a big upward stock move. Traders can take advantage of high front month volatility by buying a calendar spread - selling a front month put and buying the same strike in the following month. The maximum profit potential is reached if the stock trades at the strike price, with the front-month option decaying far faster than the more expensive longer-term option. Losses are limited to the initial trade price.

Sometimes excessive fear is expressed by extremely steep skew, when out-of-the-money puts display increasingly higher implied volatilities than at-money options. Traders who use vertical spreads can capitalize on this phenomenon. Those who are bearish can buy an at-money put while selling an out-of-the-money put. This allows the purchaser to defray some of the cost of a high priced option, though it caps the trade's profits if the stock declines below the lower strike. On the other hand, those who believe the market is excessively bearish can sell an out-of-the-money put while buying an even lower strike put. Although the trader is buying the higher volatility option, it allows him to make money as long as the stock stays above the higher strike price, while capping his loss at the difference between the two strikes.

Considerations for Exercising Call Options Prior to Expiration

INTRODUCTION

Exercising an equity call option prior to expiration ordinarily provides no economic benefit as:

  • It results in a forfeiture of any remaining option time value;
  • Requires a greater commitment of capital for the payment or financing of the stock delivery; and
  • May expose the option holder to greater risk of loss on the stock relative to the option premium.

Nonetheless, for account holders who have the capacity to meet an increased capital or borrowing requirement and potentially greater downside market risk, it can be economically beneficial to request early exercise of an American Style call option in order to capture an upcoming dividend.

BACKGROUND

As background, the owner of a call option is not entitled to receive a dividend on the underlying stock as this dividend only accrues to the holders of stock as of its dividend Record Date. All other things being equal, the price of the stock should decline by an amount equal to the dividend on the Ex-Dividend date. While option pricing theory suggests that the call price will reflect the discounted value of expected dividends paid throughout its duration, it may decline as well on the Ex-Dividend date.  The conditions which make this scenario most likely and the early exercise decision favorable are as follows:

1. The option is deep-in-the-money and has a delta of 100;

2. The option has little or no time value;

3. The dividend is relatively high and its Ex-Date precedes the option expiration date. 

EXAMPLES

To illustrate the impact of these conditions upon the early exercise decision, consider an account maintaining a long cash balance of $9,000 and a long call position in hypothetical stock “ABC” having a strike price of $90.00 and time to expiration of 10 days. ABC, currently trading at $100.00, has declared a dividend of $2.00 per share with tomorrow being the Ex-Dividend date. Also assume that the option price and stock price behave similarly and decline by the dividend amount on the Ex-Date.

Here, we will review the exercise decision with the intent of maintaining the 100 share delta position and maximizing total equity using two option price assumptions, one in which the option is selling at parity and another above parity.

SCENARIO 1: Option Price At Parity - $10.00
In the case of an option trading at parity, early exercise will serve to maintain the position delta and avoid the loss of value in long option when the stock trades ex-dividend, to preserve equity. Here the cash proceeds are applied in their entirety to buy the stock at the strike, the option premium is forfeited and the stock (net of dividend) and dividend receivable are credited to the account.  If you aim for the same end result by selling the option prior to the Ex-Dividend date and purchasing the stock, remember to factor in commissions/spreads:

Dividend Receivable $0 $200 $0 $200
Total Equity $10,000 $10,000 $9,800 $10,000 less commissions/spreads

 

SCENARIO 2: Option Price Above Parity - $11.00
In the case of an option trading above parity, early exercise to capture the dividend may not be economically beneficial. In this scenario, early exercise would result in a loss of $100 in option time value, while selling the option and buying the stock, after commissions, may be less beneficial than taking no action. In this scenario, the preferable action would be No Action.

Dividend Receivable $0 $200 $0 $200
Total Equity $10,100 $10,000 $10,100 $10,100 less commissions/spreads

  

NOTE: Account holders holding a long call position as part of a spread should pay particular attention to the risks of not exercising the long leg given the likelihood of being assigned on the short leg.  Note that the assignment of a short call results in a short stock position and holders of short stock positions as of a dividend Record Date are obligated to pay the dividend to the lender of the shares. In addition, the clearinghouse processing cycle for exercise notices does not accommodate submission of exercise notices in response to assignment.

As example, consider a credit call (bear) spread on the SPDR S&P 500 ETF Trust (SPY) consisting of 100 short contracts in the March '13 $146 strike and 100 long contracts in the March '13 $147 strike.  On 3/14/13, with the SPY Trust declared a dividend of $0.69372 per share, payable 4/30/13 to shareholders of record as of 3/19/13. Given the 3 business day settlement time frame for U.S. stocks, one would have had to buy the stock or exercise the call no later than 3/14/13 in order receive the dividend, as the next day the stock began trading Ex-Dividend. 

On 3/14/13, with one trading day left prior to expiration, the two option contracts traded at parity, suggesting maximum risk of $100 per contract or $10,000 on the 100 contract position. However, the failure to exercise the long contract in order to capture the dividend and protect against the likely assignment on the short contracts by others seeking the dividend created an additional risk of $67.372 per contract or $6,737.20 on the position representing the dividend obligation were all short calls assigned.  As reflected on the table below, had the short option leg not been assigned, the maximum risk when the final contract settlement prices were determined on 3/15/13 would have remained at $100 per contract.

Date SPY Close March '13 $146 Call March '13 $147 Call
March 14, 2013 $156.73 $10.73 $9.83
March 15, 2013 $155.83   $9.73 $8.83

Please note that if your account is subject to tax withholding requirements of the US Treasure rule 871(m), it may be beneficial to close a long option position before the ex-dividend date and re-open the position after ex-dividend.

The above article is provided for information purposes only as is not intended as a recommendation, trading advice nor does it constitute a conclusion that early exercise will be successful or appropriate for all customers or trades. Account holders should consult with a tax specialist to determine what, if any, tax consequences may result from early exercise and should pay particular attention to the potential risks of substituting a long option position with a long stock position.

Equity & Index Option Position Limits

Overview: 

Equity option exchanges define position limits for designated equity options classes.  These limits define position quantity limitations in terms of the equivalent number of underlying shares (described below) which cannot be exceeded at any time on either the bullish or bearish side of the market.  Account positions in excess of defined position limits may be subject to trade restriction or liquidation at any time without prior notification.

Background: 

Position limits are defined on regulatory websites and may change periodically.  Some contracts also have near-term limit requirements (near-term position limits are applied to the side of the market for those contracts that are in the closest expiring month issued).  Traders are responsible for monitoring their positions as well as the defined limit quantities to ensure compliance.  The following information defines how position limits are calculated;

 

Option position limits are determined as follows:

  • Bullish market direction -- long call & short put positions are aggregated and quantified in terms of equivalent shares of stock.
  • Bearish market direction -- long put & short call positions are aggregated and quantified in terms of equivalent shares of stock.

The following examples, using the 25,000 option contract limit, illustrate the operation of position limits:

  • Customer A, who is long 25,000 XYZ calls, may at the same time be short 25,000 XYZ calls, since long and short positions in the same class of options (i.e., in calls only or in puts only) are on opposite sides of the market and are not aggregated
  • Customer B, who is long 25,000 XYZ calls, may at the same time be long 25,000 XYZ puts. Rule 4.11 does not require the aggregation of long call and long put (or short call and short put) positions, since they are on opposite sides of the market.
  • Customer C, who is long 20,000 XYZ calls, may not at the same time be short more than 5,000 XYZ puts, since the 25,000 contract limit applies to the aggregate position of long calls and short puts in options covering the same underlying security. Similarly, if Customer C is also short 20,000 XYZ calls, he may not at the same time have a long position of more than 5,000 XYZ puts, since the 25,000 contract limit applies separately to the aggregation of short call and long put positions in options covering the same underlying security.

 

Notifications and restrictions:

 

IB will send notifications to customers regarding the option position limits at the following times:

  • When a client exceeds 85% of the allowed limit IB will send a notification indicating this threshold has been exceeded
  • When a client exceeds 95% of the allowed limit IB will place the account in closing only. This state will be maintained until the account falls below 85% of the allowed limit. New orders placed that would increase the position will be rejected.

 

Notes:

Position limits are set on the long and short side of the market separately (and not netted out).
Traders can use an underlying stock position as a "hedge" if they are over the limit on the long or short side (index options are reviewed on a case by case basis for purposes of determining which securities constitute a hedge).
Position information is aggregated across related accounts and accounts under common control.

 

Definition of related accounts:

IB considers related accounts to be any account in which an individual may be viewed as having influence over trading decisions. This includes, but is not limited to, aggregating an advisor sub-account with the advisor's account (and accounts under common control), joint accounts with individual accounts for the joint parties and organization accounts (where an individual is listed as an officer or trader) with other accounts for that individual.

 

Position limit exceptions:

Regulations permit clients to exceed a position limit if the positions under common control are hedged positions as specified by the relevant exchange. In general the hedges permitted by the US regulators that are recognized in the IB system include outright stock position hedges, conversions, reverse conversions and box spreads. Currently collar and reverse collar strategies are not supported hedges in the IB system. For more detail about the permissible hedge exemptions refer to the rules of the self regulatory organization for the relevant product.

OCC posts position limits defined by the option exchanges.   They can be found here.

Where can I receive additional information on options?

The Options Clearing Corporation (OCC), the central clearinghouse for all US exchange traded securities option, operates a call center to serve the educational needs of individual investors and retail securities brokers. The resource will address the following questions and issues related to OCC cleared options products:

- Options Industry Council information regarding seminars, video and educational materials;

- Basic options-related questions such as definition of terms and product information;

- Responses to strategic and operational questions including specific trade positions and strategies.

The call center can be reached by dialing 1-800-OPTIONS. The hours of operation are Monday through Thursday from 8 a.m. to 5 p.m. (CST) and Friday from 8 a.m. to 4 p.m. (CST). Hours for the monthly expiration Friday will be extended to 5 p.m. (CST).

What is the margin on a Butterfly option strategy?

Overview: 

In order for the software utilized by IB to recognize a position as a Butterfly, it must match the definition of a Butterfly exactly.  These are the 3 different types of Butterfly spreads recognized by IBKR, and the margin calculation on each:

Background: 

Long Butterfly:

Two short options of the same series (class, multiplier, strike price, expiration) offset by one long option of the same type (put or call) with a higher strike price, and one long option of the same type with a lower strike price.  All component options must have the same expiration, same underlying, and intervals between exercise prices must be equal. 

There is no margin requirement on this position.  The long option cost is subtracted from cash and the short option proceeds are applied to cash.

Short Butterfly Put:

Two long put options of the same series offset by one short put option with a higher strike price and one short put option with a lower strike price.  All component options must have the same expiration, same underlying, and intervals between exercise prices must be equal. 

The margin requirement for this position is (Aggregate put option highest exercise price - aggregate put option second highest exercise price). Long put cost is subtracted from cash and short put proceeds are applied to cash.

Short Butterfly Call:

Two long call options of the same series offset by one short call option with a higher strike price and one short call option with a lower strike price. All component options must have the same expiration, same underlying, and intervals between exercise prices must be equal.

The margin requirement for this position is (Aggregate call option second lowest exercise price - aggregate call option lowest exercise price). Long option cost is subtracted from cash and short option proceeds are applied to cash.

*Please note that Interactive Brokers utilizes option margin optimization software to try to create the minimum margin requirement. However, due to the system requirements required to determine the optimal solution, we cannot always guarantee the optimal combination in all cases.  Other option positions in the account could cause the software to create a strategy you didn't originally intend, and therefore would be subject to a different margin equation.
